I have multiple service tasks in my process. I'm not able to re-execute the job from exception point of particular task.
I'm using ''managementService.executeJob(id)'' for executing the particular job, here it is executing the process from service task1.
How to run the job from the exeception point of a process ?
Thanks in advance…

If you want to run it from the exception point, is that a service task as well?
Then you could make that service task asynchronous.
Best regards,

Ya, I made it asynchronous, This the format I have written in my process
"<serviceTask id="id" name="testTask" activiti:async="true" activiti:expression="#{test.processEvent(data)}"></serviceTask>"
It is creating a job entry in the data table whenever exception occurs, and after that I'm trying to re execute this job using
''managementService.executeJob(id)''
Its starting the process from service task one instead . Is there any other api or sysntax modification required to start the service from the exception point ?

My question is not about 'How to run jobs'. If it is possible can you please give me the relative answer.

Excuse me. I was confused by your hard to follow explanation of your problem.
>Its starting the process from service task one instead . Is there any other api or sysntax modification required to start the service from the exception point ?
Hence my response. If you have an exception in a service task that is asynchronous, it will be in a job with a retries count 0. You will need to execute the job yourself at that point. But then again, I really don't understand the problem you are describing.

I understood the asynchronous process flow, its going fine. And I faced issues because of two process engines running at same time in my system.
And is there any way to read the runtime variable data and also serialized data from act_ge_bytearray?
I mean like "SELECT * FROM act_ru_variable WHERE PROC_INST_ID_ = ?"

One more doubt, how can I pass my own exceptions messages to the activiti table. Right now when some exception occurs it is placing activiti exception message in database(ie in ACT_RU_JOB table) instead of user-defined exception message. I mean the following exception is placing when exception occurs in service task,
"Error while evaluating expression: #{server.processEvent(data)}"
but I want to place my own eception, How can I achieve this ?
